Hi Mike,

Sorry that the last build isn't working for you. Is your Pi up to date ? Have you done "sudo apt-get update" and "sudo apt-get upgrade" recently?

If your Pi is up to date and it still doesn't work, could you please do the following...

Run the the AppImage and in a terminal do "ps aux | grep cura" to find the PID of the cura process. Then do "lsof -p PID" to list all the open files that cura has and post that list here. (I don't think it contains any secrets)

[n2htt]

look like everything was up to date, here is the console output:

issue 44 console.txt

BTW the prior version works beautifully on my pi, seems a bit faster than cura running on my old window box.

Thanks Mike

Thanks for the console text file, I will compare to what I have here. If I can't solve this, I will revert back to using desktop GL for the pi build.

Could you try removing the contents of /home/pi/.cache/cura/qmlcache ? Thanks.

[smartavionics]

Also, do you have /usr/lib/arm-linux-gnueabihf/libGLESv2.so ? What does ls -l show for that file?

[n2htt]

I tried clearing the cache, but that did not help. The file does not appear to be installed on my pi

pi@raspberrypi:~ $ ls -l /usr/lib/arm-linux-gnueabihf/libGLESv2.so ls: cannot access '/usr/lib/arm-linux-gnueabihf/libGLESv2.so': No such file or directory pi@raspberrypi:~ $

[smartavionics]

Ah, that's the problem. I'll find out where that comes from, standby...

[smartavionics]

It's in a package called libgles2. Please install that and try again.

[n2htt]

Although the library doesn't show up in the directory you suggested, apt indicated that libgles2 was already installed. Just to be sure, I removed and re-installed the package, but no change of behavour.

Here is the console with the apt interactions console2.txt

[smartavionics]

So this is what I see...

[n2htt]

Problem solved! I was not seeing the files because I didn't sudo ls.

Once I could see them, I noticed that you had two soft links that I do not have. Added the soft links and now 0208 is working fine.

Hmm, weird. I don't remember creating those symlinks manually. Oh, well, glad it's working for you.

I'll close this issue now. If anyone else has a problem I will put something into the README.

I had the same problem with version Cura-mb-master-armhf-20200218.AppImage.

Following these steps, I was able to correct the problem:
